From: dave@php.net Operating system: PHP version: Irrelevant PHP Bug Type: Livedocs problem Bug description: Empty entities are not matched properly Description: ------------ Due to using + instead of * in a regex, empty entities ('') are not matched properly in mkindex.php. Case in point: phpdoc/en/contributors.ent &frontpage.editors; Results in an E_NOTICE in bookinfo. Eg: http://livedocs.phpdoc.info/index.php?l=en&q=bookinfo Patch is available here: http://www.powertrip.co.za/livedocs/viewpatch.php?patch=23 Patch also adds code to prevent the E_NOTICE from occurring and instead puts a HTML comment. -- Edit bug report at http://bugs.php.net/?id=37254&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37254&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=37254&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37254&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37254&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37254&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37254&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37254&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37254&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37254&r=support Expected behavior: http://bugs.php.net/fix.php?id=37254&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37254&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37254&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37254&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37254&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37254&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37254&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37254&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37254&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37254&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37254&r=mysqlcfg
